Shaping BMP morphogen gradients in the Drosophila embryo and pupal wing.
In the early Drosophila embryo, BMP-type ligands act as morphogens to suppress neural induction and to specify the formation of dorsal ectoderm and amnioserosa. Likewise, during pupal wing development, BMPs help to specify vein versus intervein cell fate. Here, we review recent data suggesting that these two processes use a related set of extracellular factors, positive feedback, and BMP hetero...

متن کاملShaping BMP morphogen gradients through enzyme-substrate interactions.
Bone morphogenetic proteins (BMPs) regulate dorsal/ventral (D/V) patterning across the animal kingdom; however, the biochemical properties of certain pathway components can vary according to species-specific developmental requirements. For example, Tolloid (Tld)-like metalloproteases cleave vertebrate BMP-binding proteins called Chordins constitutively, while the Drosophila Chordin ortholog, Sh...

متن کاملImaging Drosophila pupal wing morphogenesis.
Drosophila pupal (P) wing development entails a series of dynamic developmental events, such as epithelial and glial morphogenesis, that are of outstanding interest to cell biologists. Here, we first describe how to prepare P and prepupal (PP) wings for immunofluorescence microscopy. This protocol has been optimized to visualize wing epithelial architecture, such as polarized cortical domains o...
